On Jan. 8, health officials responded to a report of an unknown discharge occurring within a drainage channel along Nimitz Highway. In coordination with the Department of Transportation, the source of the discharge was found to be a damaged 10-inch gravity sewer main which was spilling into a DOT storm drain.

The City and County of Honolulu was immediately notified, responded to the sewage spill, and patched the break. The discharge of sewage ended at approximately 7:30 p.m. on Wednesday.

The total volume of raw sewage discharged at Keehi Lagoon near the Keehi Lagoon Beach Park is unknown at this time.
